Integra DPS 6.7 DVD and SACD player direct to 5.1

Is there a way that I can bypass the surround processor preamp and just connect the DVD player right to the 5.1 channel amp (a Marantz MM9000)? I see there are all the multi channel audio outputs on the back of the DVD player, so I'm thinking I can just go direct from those to the amps audio inputs. Only problem is I can't adjust the volume through the DVD player. Any thoughts?
